As above - it does depend what you tend to shoot. I've owned a good amount of the Sony FE lenses - few things to consider from my experiences
1. Do you need wide aperture or can you live with F4? if you can ... go with the 2470 F4, otherwise the 2470 GM is a very nice all around lens
2. after owning the 85mm 1.8 batis, 1.4 GM and FE 1.8 I decided to keep the FE 1.8 as it offers much better value for money and the AF is SIGNIFICANTLY faster than the GM
3. the samyang 35mm 1.4 is very well rated for the price, I would suggest that over the zeiss version
4. Sigma art lenses are out very soon, you can get the 50mm 1.4 for under £600 on pre order at the monent - probably a better shout than the zeiss for double the price
5. Don't forget you can switch to aps-c mode at any time, yes the image MP is about halved, but it does mean you get 2 focal lengths from each lens
